Description

基站间载波聚合的上行发射功率控制方法、 基站和设备 技术领域
本发明实施例涉及无线通信技术, 尤其涉及一种基站间载波聚合的上行 发射功率控制方法、 基站和设备。 背景技术
随着移动通信技术的发展, 第三代合作伙伴项目 (the 3rd Generation Partnership Project, 简称 3GPP) 对峰值数据速率以及系统带宽等提出了更高 的要求。 为了满足这些要求, 3GPP长期演进高级系统 (Long Term Evolution Advanced, 简称 LTE-A) 引入了载波聚合 (Carrier Aggregation, 简称 CA) 。 CA通过对多个连续或者非连续的分量载波 (Component Carrier, 简称 CC) 的聚合可以获取更大的带宽, 从而提高峰值数据速率和系统吞吐量。 在载波 聚合系统中, 当用户设备 (User Equipment, UE) 工作在多个载波时, 允许 eNB调度 UE在全部或部分载波上同时进行上行传输。 在这种情况下, 为了 eNB合理调度, 需要 UE上报其功率余量 (Power Headroom , 简称 PH) 。
CA中的 CC可以由同一个基站提供 (称为基站内 CA) , 也可以由不同 的基站提供(称为基站间 CA) 。 现有 LTE-A标准中, 对于站内 CA, 当功率 余量报告 (Power Headroom Reporting, 简称 PHR) 触发后, UE在任一服务 小区发送 PHR,包含分别为每个服务小区留有的功率余量等信息。基站接收 到 PHR, 可以估算 UE在每个服务小区的下行路损以及协调各服务小区的上 行资源分配。 对于基站间 CA, PHR触发后, UE在任一服务小区发送 PHR 只能被其中一个基站接收到,接收到 PHR的基站不知道其他基站的上行资源 分配情况, 无法协调各服务小区的上行资源。 从而导致传输资源的浪费, 传 输效率低的问题。 发明内容

图 1为本发明基站间载波聚合的上行发射功率控制方法实施例一的流程 图; 在本发明实施例中, UE可以从两个基站的多个小区同时接收数据, 其中 有一个主基站和一个辅基站, 主基站起到主控功能, 控制辅基站的选择, 数 据分流策略等, 辅基站主要起到分流数据的功能, 用来增加数据流量。 通常, 基站间载波聚合可以包含一个主基站和多个辅基站。 本实施例中, 主基站和 辅基站只是一种逻辑上的概念,在 UE建立连接的过程中,相对于该 UE来说 有主基站和辅基站之分, 但从基站本身来说, 它对于不同的 UE既可以是主 基站又可以是辅基站, 既能执行主基站的功能, 也能执行辅基站的功能。 本 实施例中关于主基站和辅基站的概念, 同样也适用于其他实施例中。 本发明 提供的方法由基站间载波聚合的上行发射功率控制装置执行, 该装置集成在 基站中, 本实施例提供的方法包括以下歩骤:
歩骤 101、第一基站获取 UE分配给第一基站的最大上行发射功率,其中, 最大上行发射功率为根据第二基站调度给 UE的上行资源状态确定的。
本实施例中, 第一基站获取 UE分配给第一基站的最大上行发射功率具 体为, 第一基站从第二基站或 UE接收第二基站调度给 UE的上行资源状态, 第一基站根据第二基站调度给 UE的上行资源状态确定 UE分配给第一基站的 最大上行发射功率。或者,第一基站从第二基站或 UE接收 UE分配给第一基 站的最大上行发射功率, 其中, 最大上行发射功率为第二基站或 UE根据第 二基站调度给 UE的上行资源状态确定的。
其中, 上行资源状态可以为第二基站在为 UE 建立语音业务时, 为 UE 调度的上行资源的半静态调度配置信息。 半静态调度配置信息可以包括: 半 静态调度 (Semi-Persistent Scheduling, 简称 SPS ) 配置命令、 SPS配置删除 命令、 SPS激活指示和 SPS去激活指示。
上行资源状态信息还可以为第二基站通过媒体介入控制单元 (Media Access Control Element, 简称 MAC CE) 、 无线资源控制 (Radio Resource Control, 简称 RRC) 消息或上行控制信息发送的上行资源状态, 具体地, 第 二基站可根据上行数据发送情况, 决定在一段时间内不调度 UE的上行数据, 则上行资源状态中包括第二基站不调度上行数据的时间和指示, 或者不调度 UE 的上行控制信息, 如物理层上行控制信道 (Physical Uplink Control Channel, 简称 PUCCH) 。 UE根据第二基站的上行资源状态, 能够合理的为 第一基站分配最大上行发射功率, 具体来说, 由于第二基站在一段时间内不 调度上行数据, 则可以将之前分配给第二基站的部分或全部发射功率分配给 第一基站, 增大第一基站的发射功率。
歩骤 102、 第一基站根据最大上行发射功率为 UE配置上行发射功率。 第一基站获取 UE分配的最大上行发射功率后,根据 UE分配的最大上行 发射功率为 UE合理配置上行发射功率,控制为 UE分配的上行发射功率不超 过 UE的最大上行发射功率, 或者适当的下调 UE发射功率。
本实施例提供的方法,第一基站在为 UE分配发射功率时,根据 UE分配 给第一基站的最大发射功率进行分配, 由于分配给第一基站的最大发射功率 是根据第二基站的上行资源状态信息分配的, 从而能够协调 UE分配给各个 基站的功率, 使得第一基站能够准确的为 UE分配上行发射功率, 在满足多 个基站发射功率要求的同时提高了 UE 的吞吐量。 由于各个基站之间考虑了 其他基站配置的上行资源状态, 所以分配的上行发射功率可以减少甚至避免 浪费的现象, 因而提高传输效率。
本实施例中, 第一基站可以为辅基站, 第二基站可以为主基站, 由辅基 站配合主基站的上行资源状态来分配上行发射功率。 但实际应用中, 也可以 相反, 主基站也可以配合辅基站的上行资源状态来分配上行发射功率, 或者 多个辅基站彼此之间考虑其他基站的上行资源状态。
图 2为本发明基站间载波聚合的上行发射功率控制方法实施例二的流程 图, 本实施例中, 第一基站为辅基站, 第二基站为主基站, 但本领域技术人 员可以理解, 第一基站为主基站, 第二基站为辅基站也可适用。 本实施例提 供一种在各个基站间半静态分配 UE上行发射功率的方法, 本实施例提供的 方法, 具体包括以下歩骤:
歩骤 201、第一基站从第二基站或 UE接收第二基站调度给 UE的半静态 调度配置信息。
本实施例中, 第二基站调度给 UE 的上行资源状态为第二基站在为 UE 建立语音业务时, 为 UE调度的上行资源的半静态调度(SPS)配置信息。 其 中, 半静态调度配置信息包括: SPS配置命令、 SPS配置删除命令、 SPS激 活指示和 SPS去激活指示。
半静态调度的方式一般应用于, 数据包大小比较固定, 到达时间间隔满 足一定规律的实时性业务, 比如通过 IP数据包发送实现的语音(Voice over Internet Protocal, 简称 VoIP)业务。基站在初始调度时通过物理下行控制信 道(Physical Downlink Control Channel, 简称 PDCCH)指示 UE当前的调度 信息, UE识别是半静态调度, 则保存当前的调度信息, 每隔固定的周期在 相同的时频资源位置上进行该业务数据的发送或接收。半静态调度传输, 可 以充分利用话音数据包周期性到达的特点, 一次授权, 周期使用, 可以节省 LTE系统用于调度指示的 PDCCH资源。 在业务建立初期由 RRC配置相关 的半静态调度参数, 如半静态传输时间间隔、 半静态小区的无线网络标识, 上行传输功率等。
以典型的 VoIP业务为例,其数据包到达周期为 20ms,则基站通过 PDCCH 给 UE半静态调度指示, UE即按照 PDCCH的指示进行本次调度数据的传输 或者接收, 并且在每隔 20ms 之后, 在相同的时频资源位置上进行新到达的 VoIP数据包的传输或者接收。
本实施例中, 由第二基站下发 SPS配置, 当建立 VoIP承载时, 第二基 站通过 RRC重配消息下发 SPS配置给 UE, 同时可将该 SPS配置通过第二基 站和第一基站的接口消息发送给第一基站, SPS 配置可包含半静态传输时间 间隔, 半静态调度小区无线网络标识 (SPS-C-RNTI) , 上行传输功率等。
第一基站在获取 SPS配置后, 还需要进一歩获取 SPS状态, SPS状态有 激活 /去激活两种状态。 第一基站从接收到的半静态配置信息中解析获取 SPS 状态。 以下通过具体的例子来说明第一基站如何获取 SPS状态。
UE通过使用 SPS-C-RNTI解析 PDCCH获取 SPS激活指示,并将 SPS激 活指示给第一基站,或者第二基站向 UE下发 SPS激活指示时,同时发送 SPS 激活指示给第一基站。
对于 SPS去激活状态, UE有隐式去激活和显示去激活两种方式, 隐式 去激活是指 UE自行根据实际的需要决定去激活,显示去激活指 UE接收到第 二基站发送的去激活指示时才执行去激活操作。 当 UE隐式去激活时, UE直 接向第一基站发送 SPS去激活指示。当 UE显示去激活时,第二基站在向 UE 发送 SPS去激活指示时, 同时也向第一基站发送 SPS去激活指示。 第二基站还可以通过下发 SPS配置删除命令, 取消半静态调度的方式。 当 UE接收到第二基站下发是 SPS配置删除命令,通常包含在 RRC重配消息 中, UE可发送 SPS配置删除命令给第一基站, 或者第二基站向 UE下发 SPS 配置删除命令时, 也向第一基站下发 SPS配置删除命令, 指示第一基站 SPS 配置被释放。
本实施例中, UE可以通过一种新定义的 MAC CE或者 RRC层消息将各 种 SPS指示信息发送第一基站。 第二基站通过第二基站和第一基站间的接口 消息将各种指示信息发送给第一基站。
歩骤 202、第一基站根据第二基站调度给 UE的半静态调度配置信息确定 UE分配给第一基站的最大上行发射功率。
第一基站根据第二基站调度给 UE的半静态调度配置信息确定 UE分配给 第一基站的最大上行发射功率具体为: 第一基站根据第二基站调度给 UE 的 半静态调度配置信息, 确定上行发射功率的偏移量。第一基站将偏移量与 UE 分配给第一基站的初始最大上行发射功率进行叠加, 确定为 UE分配给第一 基站的最大上行发射功率。 可以理解的是, 偏移量也可以为零, 即不需要给 第一基站增加偏移量, 这种情况下 UE分配给第一基站的初始最大上行发射 功率即为 UE分配给第一基站的最大上行发射功率。
当第一基站根据半静态调度配置信息获知第二基站在接下来的一段时间 内不调度 UE的上行数据时, 例如第一基站接收到 SPS去激活指示或者 SPS 配置删除命令时, 在确定第一基站的最大上行发射功率时增加上行功率的偏 移量, 即使用功率补偿, 将第二基站的部分发射功率分配给第一基站, 增加 第一基站的最大上行发射功率。 具体来说, 第一基站将重新计算 UE分配给 第一基站的最大发射功率 P'TMAx,eNB 1。 具体的计算方式为, 第二基站指示上 行发射功率偏移量 ΔΡΤΜΑΧ, 第一基站在计算最大上行发射功率 P'TMAx,eNB 1时, 在 UE分配给第一基站的初始最大上行发射功率 PTMAx,eNB 1的基础上加上偏移 直 ΔρχΜΑ ' §口 P,TMAX,eNBl 二 ΡτΜΑ ,βΝΒΙ + ΑρΤΜΑ 。
当第一基站根据 SPS激活指示确定第二基站有上行数据发送的时刻, 不 使用功率补偿, 即第一基站确定最大上行发射功率时, 不需要在初始最大上 行发射功率的上增加偏移量。
以下将具体说明第一基站如何确定上行发射功率的偏移量, 第一基站根 据第二基站调度给 UE的上行资源状态, 识别出第二基站在当前时刻调度给 UE的上行资源低于设定门限值时, 则确定上行发射功率的偏移量。偏移量的 数值也可以为预先配置的, 也可以根据 UE的上行资源状态动态的分配偏移 通过上述描述可知, 第一基站需要预先获取 UE分配给第一基站的初始 最大上行发射功率。本实施例中, UE分配给第一基站的初始最大上行发射功 率为根据各基站和 UE之间的下行路损或上行路损确定的初始最大上行发射 功率, 也可通过其他方式确定初始最大上行发射功率, 例如根据各基站实际 的处理能力, 指定分配给各基站的初始最大上行发射功率, 只要保证分配给 各基站的初始最大上行发射功率的总和不超过 UE的最大发射功率。
歩骤 203、第一基站获取根据最大上行发射功率重新计算的 UE的功率余 本歩骤为可选歩骤, 本实施例中, 只有当第一基站确定的最大上行发射 功率相对于历史值发生变化时, 或变化值超出预设门限值时, 第一基站获取 根据最大上行发射功率重新计算的 UE的功率余量。 具体地, 当分配给第一 基站的最大上行发射功率变化时, UE分配给第一基站的各载波的最大发射功 率也会变化, 相应地, UE的功率余量也会变化, PH是指 UE分配给各基站 每个载波的最大上行发射功率 PCMAX'C和估计出的 UE用于上行发射的上行发 射功率的差值。 UE的在载波 C上的功率余量 PH分为两种类型:
第一种类型的 PH的计算公式为:
Figure imgf000025_0001
- PPUSCH
其中, PCMA^表示 UE分配给第一基站上的载波 C的最大上行发射功率,
PPUSCH表示物理上行共享信道(Physical Uplink Shared Channel,简称 PUSCH ) 的发射功率。 这种方式中, 在同一时刻, 当在 PUSCH上发送数据时, 不在 物理上行控制信道 PUCCH上发送控制信息。
第二种类型 PH的计算公式为: PH
Figure imgf000025_0002
其中, PCMAX,C表示 UE分配给第一基站上的载波 C的最大上行发射功率, PPUSCH表示分配给物理上行共享信道 PUSCH 的发射功率, PPUc H表示分配给 PUCCH的发射功率信息。 这种方式中, 在同一时刻, 允许在 PUSCH上发送 数据的同时在 PUCCH上发送控制信息。
本实施例中,由于分配给第一基站的最大上行发射功率 P Ax^m变化了, 在初始最大上行发射功率的基础上增加了偏移量 ΔΡΤΜΑΧ,第一基站的各载波 的最大上行发射功率也相应的变化, 本实施例中以第一基站只有一个载波为 例, 因此 P'CMAX^PCMAX^+ΔΡΤΜΑΧ,即在载波 C的最大上行发射功率的基础上 增加了上行发射功率偏移量 ΔΡΤΜΑΧ, 则 PH' = P'cMAX,c - PPUSCH -PPUCCH ' 或者 PH' Z
Figure imgf000026_0001
当然, 第一基站也可以有多个载波, 可对每个载波都 适当的增加功率偏移量, 保证各载波增加后最大上行发射功率之和不会超过
UE所允许的最大上行发射功率。
通过上述方法, 可以根据实际的情况, 调整基站对应的载波的发射功率, 使各载波的资源都能够得到最大的利用, 提高上行数据的传输效率和 UE的 吞吐量。 可以理解的是, 功率余量也可以由 UE计算, 并上报给第一基站。
歩骤 204、第一基站根据 UE分配给第一基站的最大上行发射功率、各载 波的最大上行发射功率及功率余量为 UE配置上行发射功率。
第一基站根据 P' TMAX,eNBl 、 ^ CMAX.,c和 PH'为 UE分配上行发射功率使用。 具体来说, 第一基站比较 P' TMAX,eNBl和 P, CMAX.,c的大小, 选择两者中最小的值为 UE分配上行发射功率,保证分配给 UE的最大上行发射功率不会超过两者中最 小值。
本实施例适用的一种主要场景是第二基站只负责语音业务数据的下发和 接收, 第一基站负责其他业务的下发和接收, 这样考虑的原因是本发明中将 第二基站作为主基站, 而主基站通常覆盖范围广, 能更好的支持语音业务的 连续性, 提高用户的感知。
本实施例提供的方法, 在各个基站间采用半静态调度的方式为各个基站 分配上行发射功率, 由第二基站下发半静态调度配置, 第一基站在为 UE分配 上行发射功率时, 根据半静态调度配置来确定 UE分配给自身的最大上大上行 发射功率。 第一基站能够合理的调整自己的上行发射功率, 提高 UE的吞吐量 和上行资源的利用率。
图 3为本发明基站间载波聚合的上行发射功率控制方法实施例三的流程 图, 本实施例中初始最大上行发射功率根据上行路损和下行路损计算得到, 并且详细描述如何根据上行路损和下行路损计算 UE分配给各基站的初始最 大上行发射功率, 本实施例提供的方法包括以下歩骤:
歩骤 301、 第一基站获取 UE分配给第一基站的初始最大上行发射功率, 其中, 初始最大上行发射功率根据各基站和 UE之间的下行路损或上行路损 确定。
本实施例中, 第一基站为辅基站, 第二基站为主基站, 对于 UE来说, 在每次接入过程中, 只有一个主基站, 但是可以有多个辅基站。 第一基站获 取 UE分配给第一基站的初始最大上行发射功率, 具体可通过以下三种方式 来实现:
在第一种实现方式中,第一基站接收 UE上报的 UE分配给第一基站的初 始最大上行发射功率, 其中, 初始最大上行发射功率为 UE根据各基站和 UE 之间的下行路损比例从 UE的最大上行发射功率中分配的。
在第二种实现方式中, 第一基站接收第二基站发送的 UE分配给第一基 站的初始最大上行发射功率, 其中, 初始最大上行发射功率为第二基站根据 各基站和 UE之间的下行路损比例从 UE的最大上行发射功率中分配的。
第三种实现方式中, 第一基站获取第二基站发送的各基站和 UE之间的 上行路损; 第一基站根据各上行路损的比例, 从 UE 的最大上行发射功率中 计算获得 UE分配给第一基站的初始最大上行发射功率。 第一基站不仅需要 获取第二基站发送的各基站和 UE 之间的上行路损, 还需要自行计算和 UE 之间的上行路损, 具体的, 首先, 第一基站接收 UE发送的探测参考信号; 然后,第一基站根据探测参考信号的接收功率和发送功率确定第一基站和 UE 之间的上行路损; 最后, 第一基站将自身与 UE之间的上行路损上报给第二 基站, 以便第二基站转发给其他基站。 这样, 每个基站都互相知道和 UE之 间的上行路损, 并且能够根据上行路损的比例从 UE 的最大上行发射功率中 分配功率。
歩骤 302、第一基站根据初始最大上行发射功率为 UE分配上行发射功率。 本实施例中, 第一基站获取 UE分配给第一基站的初始最大上行发射功 率后, 还可以根据实际的需要或者第二基站的配置在初始最大上行发射功率 中增加补充偏移量, 补充偏移量可以由第二基站配置给第一基站, 当第一基 站需要和 UE之间进行大量的数据传输,而 UE与第二基站之间的数据传输量 较少时, 可以通过增加在第一基站的上行发射功率, 可以增加 UE分配给第 一基站的最大上行发射功率, 从而能够增加 UE 的吞吐量, 提高整个网络的 利用率, 而且不会干扰到第二基站。 本实施例中, 第一基站可以按照设定周期, 或在上行路损或下行路损发 生变化时, 或在路损变化值超出设定门限值时, 获取 UE分配给第一基站的 初始最大上行发射功率。
本实施例提供的方法, 第一基站在为 UE分配上行发射功率时, 根据获 取的初始最大上行发射功率来确定上行发射功率, 由于初始最大上行发射功 率是根据各基站和 UE之间的上行路损确定的, 因此, 能够保证分配给各基 站的初始最大上行发射功率不超过 UE 的实际要求, 而且能够根据各基站和 UE之间的路损情况, 为各基站分配合适的发射功率, 提供 UE的吞吐量和上 行资源的利用率。
图 4为本发明基站间载波聚合的上行发射功率控制方法实施例四的流程 图, 本实施例提供的方法由基站间载波聚合的上行发射功率控制装置执行, 该装置集成在基站中。 本实施例提供的方法具体包括以下歩骤:
歩骤 401、 第二基站将自身调度给 UE的上行资源状态提供给第一基站, 以便第一基站根据第二基站调度给 UE的上行资源状态,确定 UE分配给第一 基站的最大上行发射功率。
具体地, 第二基站可以通过以下两种方式将上行资源状态提供给第一基 站:
第一种方式: 第二基站将自身调度给 UE 的上行资源状态发送给第一基 站,或者将自身调度给 UE的上行资源状态通过 UE发送给第一基站。第二基 站将自身调度给 UE的上行资源状态通过 UE发送给第一基站具体为:第二基 站将自身调度给 UE的上行资源状态, 通过 MAC CE、 RRC消息或上行控制 信息发送给 UE, 以通过 UE发送给第一基站。
在第一种方式中, 第二基站根据 UE上行发送情况, 可决定在一段时间 内不在第二基站调度 UE上行数据, 并下发相关指示给 UE, 指示 UE在多长 时间内不调度 UE的上行数据,也可以指示在一段时间内不调度 UE的上行控 制信息 PUCCH等。第二基站确定自身调度给 UE的上资源状态,并下发给第 一基站或者 UE, 具体地, 上行资源状态中包括第二基站没有上行数据调度的 指示和相应时间等。
第二种方式:第二基站为 UE建立语音业务时,为 UE配置上行资源的半 静态调度, 并且将半静态调度配置信息发送给第一基站, 或者发送给 UE, 以 通过 UE发送给第一基站。 其中, 半静态调度配置信息包括: SPS配置命令、 SPS配置删除命令、 SPS激活指示和 SPS去激活指示。
歩骤 402、 第二基站根据上行资源状态为 UE调度上行资源。
第二基站根据自身分配给 UE的上行资源状态,确定为 UE调度上行资源, 当第二基站自身没有数据要调度的情况下, 可以适当的降低最大上行发射功 率, 将部分发射功率分配给第一基站, 增大第一基站的上行发射功率, 第二 基站可以配置给第一基站的上行功率偏移量的值, 并下发给第一基站和 UE, 以便第一基站能够调整上行发射功率。
本实施例提供的方法, 第二基站将自身调度给 UE 的上行资源状态发送 给第一基站, 以便第一基站根据第二基站的上行资源状态合理的调整自身的 上行发射功率, 增大 UE的吞吐量, 提高上行资源的利用率。
图 5为本发明基站间载波聚合的上行发射功率控制方法实施例五的流程 图。 本实施例提供的方法能够动态的调整 UE 的上行发射功率, 本实施例中 第一基站为辅基站, 第二基站为主基站, 具体包括以下歩骤:
歩骤 501、 第二基站配置预设功率信息, 预设功率信息至少包括第二基 站在下一时刻预设配置给 UE的上行发射功率。
第二基站根据下一时刻实际需要调度的数据的情况, 预先配置预设功率 信息。 本实施例中, 第二基站向第一基站发送的预设功率信息可以包括: UE 的最大发射功率、 UE分配给第二基站的最大发射功率、 UE的上行控制信息 调度状态、 UE分配给第二基站各载波的最大发射功率和第二基站采用的上行 发射功率的偏移量。预设功率信息还可以包括, UE是否有上行控制信息的调 度, 是否上行数据和上行控制信息调度并行。
歩骤 502、 第二基站向第一基站发送预设功率信息, 以便第一基站根据 预设功率信息确定第一基站在下一时刻配置给 UE的上行发射功率。
第二基站可以在每一个时间传输间隔 TTI都向第一基站发送预设功率信 息, 以便于第一基站能够根据预设功率信息准确的为 UE 分配上行功率。 当 第二基站在下一时刻没有数据调度,则可以在预设功率信息中携带指示信息, 通知第一基站下一时刻没有数据调度,
本实施例中, 当第二基站的预设功率信息变化频率不大的情况下, 为了 降低发送预设功率信息的资源, 第二基站不用每一 ΤΉ都向第一基站发送预 设功率信息, 可以在预设功率信息中携带一段时间的预设功率信息。
歩骤 503、 第一基站接收第二基站发送的预设功率信息, 预设功率信息 至少包括第二基站在下一时刻预设配置给 UE的上行发射功率。
第一基站根据第二基站发送的预设功率信息, 在下一时刻给 UE分配上 行发射功率时, 可以适当增大分配给第一基站的发射功率。
歩骤 504、 第一基站根据预设功率信息确定第一基站在下一时刻配置给 UE的上行发射功率。
具体地, 第一基站根据预设功率信息, 若 UE分配给第二基站的最大发 射功率较小, 则可以增加下一时刻分配给 UE 的上行发射功率, 但是必须保 证分配给第一基站和第二基站的最大发射功率的总和不超过 UE 的最大发射 功率。 若 UE分配给第二基站的最大发射功率考虑了功率补偿, 在在预设功 率信息中还包括第二基站采用的上行发射功率的偏移量。 并且根据 UE分配 给第二基站各载波的最大发射功率, 调整分配给第一基站的各载波的最大发 射功率, 以及功率余量。 具体计算方法可以参照实施例二中的描述。 第一基 站在接收到第二基站下一时刻的预设功率信息后, 调整自身下一时刻配置给 UE的上行发射功率,如果第二基站下一时刻配置给 UE的上行发射功率较小, 则第一基站可以适当增加自身下一时刻配置给 UE的发射功率,保证 UE资源 能够合理的利用, 如果第二基站下一时刻配置给 UE 的上行发射功率较大, 则第一基站可以适当减少自身下一时刻配置给 UE的发射功率。
本实施例提供的方法, 第一基站能够根据第二基站上报下一时刻预设配 置给 UE的上行发射功率,实时的调整第一基站在下一时刻分配给 UE的上行 发射功率, 从而能够更准确合理的分配 UE在各基站的上行发射功率, 提高 UE的上行速率和吞吐量。
图 6为本发明基站间载波聚合的上行发射功率控制方法实施例六的流程 图。 本实施例提供的方法, 包括以下歩骤:
601、第二基站获取 UE分配给第二基站的初始最大上行发射功率,其中, 初始最大上行发射功率根据各基站和 UE之间的下行路损或上行路损确定。
第二基站具体通过以下方法获取 UE分配给第二基站的初始最大上行发 射功率。
第一种方法,第二基站接收 UE上报的 UE分配给第二基站的初始最大上 行发射功率,其中,初始最大上行发射功率为 UE根据各基站和 UE之间的下 行路损比例从 UE的最大上行发射功率中分配的。
第二种方法,第二基站接收 UE上报的 UE分配给各基站的初始最大上行 发射功率; 或第二基站接收 UE上报的各基站的下行路损, 并根据各下行路 损的比例从 UE的最大上行发射功率中计算获得 UE分配给各基站的初始最大 上行发射功率; 第二基站将各初始最大上行发射功率发送给对应的基站。
第三种方法, 第二基站获取各基站发送的基站和 UE之间的上行路损; 第二基站根据各上行路损的比例, 从 UE的最大上行发射功率中计算获得 UE 分配给各基站的初始最大上行发射功率。 第二基站将各初始最大上行发射功 率发送给对应的基站。 第二基站还需要计算自身和 UE之间的上行路损, 具 体通过以下方法计算, 第二基站接收 UE发送的探测参考信号, 根据探测参 考信号的接收功率和发送功率确定第二基站和 UE之间的上行路损。
602、第二基站在分配给辅基站的初始最大上行发射功率中增加补充偏移 本歩骤为可选歩骤, 第二基站可以根据实际的情况确定是否需要在分配 给辅基站的初始最大上行发射功率中增加补充偏移量。 若预先配置了补充偏 移量, 则第二基站在分配给第一基站的初始最大上行发射功率中增加补充偏 移量, 相应地, 第二基站减少分配给自身的功率偏移量, 减少的量和分配给 辅基站的补充偏移量是相等的。 若没有配置, 则不需要增加补充偏移量。
603、 第二基站根据初始最大上行发射功率为 UE分配上行发射功率。 对于本歩骤来说, 若执行了歩骤 602, 则本歩骤中的初始最大上行发射 功率为增加补充偏移量后得到初始最大上行发射功率, 若没有执行歩骤 602, 则本歩骤中的初始最大上行发射功率是指根据路损计算得到的初始最大上行 发射功率。
本实施例中, 第二基站按照设定周期, 或在上行路损或下行路损发生变 化时, 或在路损变化值超出设定门限值时, 获取 UE分配给第二基站的初始 最大上行发射功率。
图 7为本发明基站间载波聚合的上行发射功率控制方法实施例七的流程 图,本实施例提供的方法可由基站间载波聚合的上行发射功率控制装置执行, 该装置集成在 UE中, 本实施例提供的方法包括以下歩骤: 歩骤 701、 UE获取第二基站调度给 UE的上行资源状态。
具体的, UE通过如下方式获取第二基站调度给 UE的上行资源状态: UE 接收第二基站通过 MAC CE、RRC消息或上行控制信息发送的上行资源状态; 或 UE接收第二基站发送的 SPS配置命令、 SPS配置删除命令、 SPS激活指 示和 SPS去激活指示, 作为上行资源状态; 或 UE识别第二基站是否在设定 时间内没有调度上行资源, 根据识别结果确定上行资源状态。
歩骤 702、 UE向第一基站上报第二基站调度给 UE的上行资源状态, 以 使第一基站根据上行资源状态确定 UE分配给第一基站的最大上行发射功率; 或 UE根据第二基站调度给 UE的上行资源状态确定 UE分配给第一基站的最 大上行发射功率, 并上报给第一基站。
本实施例中, UE在获取到第二基站调度给 UE的上行资源状态后, UE 可以将上行资源状态上报给第一基站, 由第一基站确定 UE分配给第一基站 的最大上行发射功率。 当然, UE也可以自己根据上行资源状态确定 UE分配 给第一基站的最大上行发射功率, 并上报给第一基站。
以下将通过具体的例子说明 UE如何根据第二基站调度的上行资源状态 确定 UE分配给第一基站的最大上行发射功率。 首先, UE根据第二基站调度 给 UE的上行资源状态, 确定上行发射功率的偏移量。 然后, UE将偏移量与 UE分配给第一基站的初始最大上行发射功率进行叠加,确定为 UE分配给第 一基站的最大上行发射功率。 其中, 偏移量的数值为预先配置的或第二基站 通过网络信令下发的。
本实施例中, UE按照设定周期, 或在上行路损或下行路损发生变化时, 或在路损变化值超出设定门限值时, 获取 UE分配给各基站的初始最大上行 发射功率。
本实施例提供的方法,UE通过获取第二基站调度给 UE的上行资源状态, 并上报给第一基站, 以使第一基站根据第二基站调度给 UE上行资源状态最 大上行发射功率,或者 UE根据第二基站调度给 UE的上行资源状态确定分配 给第一基站的最大上行发射功率, 并上报给第一基站。 从而保证了分配给第 一基站的最大上行发射功率是根据各个基站之间的资源确定的, 能够合理为 各个基站分配最大上行发射功率, 提高 UE的吞吐量和网络的利用率。
在上述歩骤 702中, UE根据第二基站调度给 UE的上行资源状态确定 UE分配给第一基站最大上行发射功率,具体是通过确定上行发射功率的偏移 量, 并在 UE分配给第一基站的初始最大上行发射功率的基础上叠加该偏移 量。 对于初始最大上行发射功率, UE可以通过多种方法确定, UE可以根据 各基站和 UE之间的下行路损或上行路损确定的初始最大上行发射功率, 也 可通过其他方式确定初始最大上行发射功率, 例如根据各基站实际的处理能 力, 指定分配给各基站的初始最大上行发射功率, 只要保证分配给各基站的 初始最大上行发射功率的总和不超过 UE的最大发射功率。
以下将简单说明 UE怎么确定初始最大上行发射功率。 在一种实现方式 中, UE向基站上报 UE和基站之间的下行路损, 以使基站根据下行路损确定 UE在基站分配的初始最大上行发射功率。 UE向基站上报 UE和基站之间的 下行路损包具体为: UE首先测量与各基站之间的下行路损, 然后向第二基站 上报 UE和各基站之间的下行路损。
在另外一种实现方式中, UE根据与基站之间的下行路损, 确定 UE分配 给基站的初始最大上行发射功率, 并上报给基站。 UE根据与基站之间的下行 路损, 确定 UE分配给基站的初始最大上行发射功率, 并上报给基站具体为:
UE 首先测量与各基站之间的下行路损, 根据与各基站之间的下行路损的比 例, 从 UE的最大上行发射功率中计算获得分配给各基站的初始最大上行发 射功率, 最后将确定的初始最大上行发射功率上报给各基站, 或上报给第二 基站, 以便通过第二基站转发给各基站。
在上述两种方式中, UE测量与各基站之间的下行路损具体为, UE接收 各基站发送的探测参考信号, 根据探测参考信号的接收功率和发送功率确定 与各基站之间的下行路损。
本实施例中, 为了能够提高合理分配各基站的初始最大上行发射功率, 提高 UE吞吐量, UE确定分配给各基站的初始最大上行发射功率之后, 还在 分配给第一基站的最大上行发射功率中增加补充偏移, 相应地减少分配给第 二基站的初始最大上行发射功率。
本实施例中, UE按照设定周期, 或在上行路损或下行路损发生变化时, 或在路损变化值超出设定门限值时, 获取 UE分配给各基站的初始最大上行 发射功率。
图 8为本发明基站间载波聚合的上行发射功率控制方法实施例八的流程 图, 本实施例中详细描述如何根据下行路损确定分配各基站的初始最大上行 发射功率。 本实施例中, 第一基站为辅基站, 第二基站为主基站, 具体包括 以下歩骤:
歩骤 801、 UE测量与各基站之间的下行路损。
UE 可以测量探测参考信号的下行接收功率, 通过计算探测参考信号
( Sounding Reference Signal, 简称 SRA) 的发射功率和接收功率之差得到下 行路损,其中,探测参考信号可以为小区参考信号 CRS Cell Reference Signal), 各个基站都向 UE发送参考信号,并在向 UE发送的信息中携带参考信号的发 射功率, UE接收到各基站发送的参考信号后, 测量各参考信号的接收功率, 各参考信号的发射功率减去相应的接收功率, 就得到 UE和各基站间的下行 路损。
以下将以 UE具有一个主基站和一个辅基站为例来进行说明, 第一基站为 辅基站, 第二基站为主基站。 假设 UE和第一基站之间的下行路损为 P NB1, UE和第二基站之间的下行路损为 ΡΙ^ΝΒ2.。
歩骤 802、 UE根据与各基站之间的下行路损比例, 从 UE的最大上行发射 功率中计算获得分配给各基站的初始最大上行发射功率。
假设 UE的最大发射功率为 PTMAX, UE在第一基站下的路损比例为 α = PLeNBi/ (PLENB 1+PLENB2) , 则 UE在分配给第一基站的初始最大上行发射功率为
PTMAX,eNBl = 。 * PTMAX, UE分配给第二基站
Figure imgf000034_0001
= (1- α )* ΡΤΜΑχ。
本实施例中, 初始最大上行发射功率可以为直接根据下行路损计算得到 的值, 或者为在初始最大上行发射功率中增加补充偏移量得到的修正后的初 始最大上行发射功率。 可选的, 由于第一基站一般为小型基站, 可增加一个 补充偏移量给 UE, 使 UE增加在第一基站的发射功率, 通过增加在第一基站 的发射功率则可增加 UE 的吞吐量而并不干扰第二基站。 例如补充偏移量为 β = X dBm, 则分配给第二基站的初始最大上行发射功率为 PTMAX,ENB2 = α * ΡΤΜΑΧ - β, 分配给第一基站的初始最大上行发射功率为 PTMAx,eNB1 = (1- α )* ΡΤΜΑχ + β。 此外, 补充偏移量也可以以其他形式表述, 如比例的形式, 将第 二基站的百分之十的功率作为补充偏移量, 配置给第一基站。 补充偏移量由 第二基站配置给 UE,例如将补充偏移量携带在无线资源控制连接重配消息发 送给 UE。
歩骤 803、 UE将确定的初始最大上行发射功率上报给各基站, 或上报给 第二基站, 以便通过第二基站转发给各基站。
UE将计算得到的分配给第一基站和第二基站的初始最大上行发射功率 为上报给第一基站和第二基站, 以供第一基站和第二基站分配上行发射功率 使用。 UE也可以将各基站的初始最大上行发射功率上报给第二基站, 第二基 站通过与第一基站之间的接口信息将分配给各基站的初始最大上行发射功率 上报给各第二基站。
具体地, UE可以通过专用的无线资源控制连接消息将初始最大上行发射 功率上报给基站,也可以使用 MAC CE上报,例如可以定义一种新的 MAC CE, 如表一所示:
表一
Figure imgf000035_0001
本实施例中, UE按照设定周期, 或在下行路损发生变化时, 或在路损变 化值超出设定门限值时, 获取 UE分配给各基站的初始最大上行发射功率。
本实施例提供的方法, 由 UE计算和每个基站之间的下行路损, 并根据下 行路损的比值从 UE的最大上行发射功率中为各基站分配初始最大上行发射 功率, 并将计算好的 UE分配给各基站的最大上行发射功率发送给各个基站, 使得各基站根据初始最大上行发射功率为 UE分配上行发送功率和调度资源 用。 本实施例提供的方法, UE在为各基站分配功率时, 综合考虑各个基站的 下行路损, 能够很好的协调各个基站间的功率, 提高 UE的吞吐量和上行资源 的利用率。
图 9为本发明基站间载波聚合的上行发射功率控制方法实施例九的流程 图。 如图所示, 包括以下歩骤:
歩骤 901、 UE测量与各基站之间的下行路损。
本实施例中, UE也是接收各基站发送的参考信号 (Reference Signal) , 如小区参考信号 (Cell Reference SignalCRS), 根据参考信号的接收功率和发 送功率确定与各基站之间的下行路损,具体算法可参照实施例九的实现方式, 这里不再赘述。
歩骤 902、 UE向第二基站上报 UE和各基站之间的下行路损。
本实施例中, 第二基站为主基站, 即 UE将计算好的下行路损上报给主基 站, UE可通过专用无线资源控制消息, 如定义一种新的 RRC下行路损上报消 息。 当 UE接收到第一基站的配置消息后, 触发测量与各基站间的下行路损并 上报, 或者当第二基站配置第一基站给 UE时, 触发下行路损上报请求消息给 UE, UE根据该请求消息测量并上报下行路损。
由于 UE是移动的,所以测量到的下行路损是变化的,当下行路损变化时, 应重新上报变化后的路损值, 第二基站获取更新后的路损信息, 重新计算分 配给各基站的初始最大上行发射功率。 UE触发的条件可以有:
周期性触发, 网络侧下发配置的周期给 UE, UE按照网络侧的配置, 周期 性计算并上报在各基站的下行路损。
事件性触发, 如网络侧配置下行路损或者最大发射功率变化的门限值, 当 UE检测到下行路损变化超过了门限值, 则触发上报在各基站的下行路损。 又如网络侧配置基站间下行路损的差值门限, 当第一基站和第二基站间路损 之差变化超过该门限时, 触发 UE上报在各基站的下行路损。 又如网络侧配置 基站间下行路损的比值门限, 当第一基站和第二基站间路损间的比值变化超 过该门限时, 触发 UE上报在个基站的下行路损。
网络侧也可周期性下发下行路损请求消息, UE根据网络侧的请求上报。 歩骤 903、 第二基站接收 UE上报的各基站的下行路损, 并根据各下行路 损的比例从 UE的最大上行发射功率中计算获得 UE分配给各基站的初始最大 上行发射功率。
本实施例中, 第二基站还需要获取 UE的最大上行发射功率, 具体地, 第 二基站可根据 UE的能力信息中包含的 UE的类型确定 UE的最大发射功率。 在 UE刚接入网络后, UE向第二基站上报 UE能力信息, UE能力信息中包括 UE 的类型, UE所支持的频点等信息。对于不同类型的 UE支持的发射容量和功率 是不同的, 因此, 根据 UE的类型, 能够确定 UE的最大上行发射功率。
在确定 UE的最大上行发射功率后,第二基站根据各基站和 UE之间的下行 路损比例从 UE的最大上行发射功率中分配的。具体方法可以参照实施例九中 UE计算初始最大上行发射功率的方法进行计算, 这里不再赘述。
歩骤 904、 第二基站将各初始最大上行发射功率发送给对应的基站。 本歩骤中, 第二基站将分配好的各第二基站的初始最大上行发射功率下 发给对应的基站。 第二基站可通过第二基站和第一基站之间的接口消息, 如 X2接口消息下发给第一基站。第一基站接收第二基站发送的 UE分配给第一基 站的初始最大上行发射功率, 第一基站根据分配好的 UE在初始最大上行发射 功率对 UE进行资源的分配和调度。
本实施例中, UE将各基站的下行路损上报给第二基站, 由第二基站根据 各下行路损的比例从 UE的最大上行发射功率中计算获得 UE分配给第一基站 的初始最大上行发射功。 可以理解的是, UE也可以向第一基站上报各基站的 下行路损, 第一基站接收 UE上报的各基站的下行路损, 并根据各下行路损的 比例从 UE的最大上行发射功率中计算获得 UE分配给第一基站的初始最大上 行发射功。 第一基站为辅基站, 各辅基站分别计算分配给各自的初始最大上 行发射功率, 并将各自的初始最大上行发射功率上报给主基站。
本实施例提供的方法, 由 UE计算和每个基站之间的下行路损, 并将下行 路损上报给第二基站, 由第二基站根据下行路损的比值为各基站分配初始最 大上行发射功率, 并对应发送给各个基站。 本实施例提供的方法, 第二基站 在为各基站分配功率时, 综合考虑各个基站的下行路损, 根据各基站的实际 能力协调各个基站间的功率, 提高 UE的吞吐量和上行资源的利用率。
图 10为本发明基站间载波聚合的上行发射功率控制方法实施例十的流程 图, 包括以下歩骤: 歩骤 1001、 各基站分别测量与 UE之间的上行路损。
各基站测量 UE发送的上行参考信号, 如探测参考信号 (Sounding Reference) 的接收功率, 上行参考信号接收功率和发射功率的差值即为上行 路损。 具体地, 第一基站接收 UE发送的探测参考信号, 第一基站根据探测参 考信号的接收功率和发送功率确定第一基站和 UE之间的上行路损。第二基站 用同样的方法计算上行路损。
歩骤 1002、 第一基站向第二基站上报自身和 UE之间的上行路损。
本实施例中, 各基站都自行计算和 UE之间的上行路损, 第一基站并将自 身与 UE之间的上行路损上报给第二基站。以便第二基站根据各基站和 UE之间 的上行路损确定初始最大上行发射功率。 第一基站可通过第一基站和第二基 站之间的 X2接口消息上报上行路损, 该接口消息可以为一种新定义的专用消 息。第一基站可在第二基站的请求下上报上行路损, 也可在上行路损变化后, 自行上报, 或者根据网络侧的配置周期性上报。
歩骤 1003、 第二基站接收各基站发送的基站和 UE之间的上行路损, 根据 各上行路损的比例从 UE的最大上行发射功率中计算获得 UE分配给各基站的 初始最大上行发射功率。
以下将通过具体的例子说明第二基站如何根据各上行路损比例计算分配 给各基站的初始最大上行发射功率。 本实施例中, 以 UE只有一个主基站和 一个辅基站为例。 假定 UE的最大发射功率为 PTMAX, UE和第一基站之间的 上行路损为 PLeNB1, UE和 SeNB之间的上行路损为 PTMAX,eNB2, UE在 SeNB 下的初始最大上行发射功率为 PTMAX,eNB2, UE在 PeNB下的初始最大上行发 射功率 PTMAx,eNB1。 PeNB可根据各上行路损的比例值来计算的分配给各基站 的初始最大上行发射功率, α上行路损的比例, ct = PLeNB1/ (PLeNB1+PLeNB2), 则 UE在 PeNB下的最大发射功率为 PTMAx,eNB1 = α * PTMAX, UE在辅 eNB下 的最大发射功率为 PTMAx,eNB2 = (1- α )* ΡΤΜΑΧ
本实施例中, 第二基站也需要预先获取 UE的最大上行发射功率, 具体方 式可参照实施九中的描述。
可选的, 本歩骤中第二基站在根据上行路损确定各基站的初始最大上行 发射功率后, 可配置一个补充偏移量给第一基站, 使 UE增加在第一基站的 发射功率, 通过增加在第一基站发射功率来增加 UE的吞吐量而并不干扰第 二基站。 例如补充偏移量为 i5 = X dBm, 则第二基站的初始最大上行发射功率 为 PTMAx,eNB2 = α * ΡΤΜΑΧ— β; 第一基站的初始最大上行发射功率为
ΡτΜΑΧ,εΝΒΐ = (1- α :)* ΡΤΜΑχ + β。此外, 补充偏移量也可以以其他形式表述, 如 比例的形式, 本实施例不做限制。
歩骤 1004、 第二基站将各初始最大上行发射功率发送给对应的基站。 第二基站通过与第一基站之间的接口, 将各初始最大上行发射功率发送 给对应的基站。 以供第一基站根据该初始最大上行发射功率调整自身的上行 发射功率。
本实施例提供的方法, 由各基站分别计算和 UE之间的上行行路损, 第一 基站并将上行路损上报给第二基站, 由第二基站根据上行路损的比值为各基 站分配初始最大上行发射功率, 并对应发送给各个基站。 本实施例提供的方 法, 第二基站在为各基站分配功率时, 综合考虑各个基站的下行路损, 根据 各基站的实际能力协调各个基站间的功率, 提高 UE的吞吐量和上行资源的利 用率。
图 11为本发明基站间载波聚合的上行发射功率控制方法实施例十一的流 程图, 具体包括以下歩骤, 本实例提供的方法, UE根据主基站是否有上行数 据的调度来确定上行发射功率。 具体包括以下歩骤:
歩骤 1101、 第二基站向 UE发送上行资源状态。
本实施例中, 第二基站根据 UE上行发送情况, 可决定在一段时间内不在 第二基站调度 UE上行数据, 并下发相关指示给 UE, 指示 UE在多长时间内不 调度 UE的上行数据,也可以指示在一段时间内不调度 UE的上行控制信息,如 PUCCH等。则第二基站确定自身调度给 UE的上资源状态,并下发给第一基站 或者 UE, 具体地, 上行资源状态中包括第二基站没有上行数据调度的指示和 相应时间等。
具体地, 第二基站通过 MAC CE、 RRC消息或上行控制信息发送的上行 资源状态。
歩骤 1102、第二基站根据 UE的上行资源状态确定 UE分配给各基站的最大 上行发射功率及功率余量。
具体地, UE根据述第二基站调度给 UE的上行资源状态,确定上行发射功 率的偏移量, 当第二基站在某一段时间内没有数据调度时, UE将偏移量与 UE 分配给第一基站的初始最大上行发射功率进行叠加, 确定为 UE分配给第一基 站的最大上行发射功率。 例如, UE确定的上行发射功率偏移量为 ΔΡΤΜΑΧ, UE 分配给第一基站的初始最大上行发射功率 PTMAX,eNB1,则 UE分配给第一基站的 最大上行发射功率 P' TMAX,eNBl为 P, TMAX,eNBl― PTMAX,eNBl + ΔΡΤΜΑΧ。本实施例中, 功率余量可以由网络侧配置给 UE ,也可以携带在第二基站发送给 UE的上行资 源状态中。
当 UE分配给第一基站的最大上行发射功率变化后, UE分配给第一基站 的各载波的最大上行发射功率也变化了, 假设上一时刻 UE分配给第一基站 的各载波的最大上行发射功率为 PCMAX,。, 重新计算的 UE分配给第一基站的 载波的最大上行发射功率 P' CMAX,c为 P, CMAX,c二 PcMA ,c+ApTMA , ΔρτΜΑ 为上丁 发射功率的偏移量。第一基站的功率余量为,则 PH' = P'CMAX,C - PPUSCH -PPUCCH 或者 PH' = P,CMAX,c - PpUSCH°
歩骤 1 103、 UE将计算好的分配给第一基站的最大上行发射功率、 各载波 的最大上行发射功率及功率余量上报给第一基站。
UE将更新后的分配给第一基站的 P'TMAx,eNB 1、 P'CMAX,C及 PH'—同上报 给第一基站, 供第一基站调度和分配 UE的上行功率使用。
本实施例提供的方法, 由 UE计算和每个基站之间的下行路损, 并将下行 路损上报给第二基站, 由第二基站根据下行路损的比值为各基站分配初始最 大上行发射功率, 并对应发送给各个基站。 本实施例提供的方法, 第二基站 在为各基站分配功率时, 综合考虑各个基站的下行路损, 根据各基站的实际 能力协调各个基站间的功率, 提高 UE的吞吐量和上行资源的利用率。

其中, 功率获取模块 1 1, 用于获取用户设备 UE分配给第一基站的最大 上行发射功率, 其中, 最大上行发射功率为根据第二基站调度给 UE 的上行 资源状态确定的。
第一基站从第二基站或 UE接收第二基站调度给 UE的上行资源状态,第 一基站根据第二基站调度给 UE的上行资源状态确定 UE分配给第一基站的最 大上行发射功率。或者,第一基站从第二基站或 UE接收 UE分配给第一基站 的最大上行发射功率, 其中, 最大上行发射功率为第二基站或 UE根据第二 基站调度给 UE的上行资源状态确定的。
其中, 上行资源状态可以为第二基站在为 UE 建立语音业务时, 为 UE 调度的上行资源的半静态调度配置信息。半静态调度配置信息可以包括: SPS 配置命令、 SPS配置删除命令、 SPS激活指示和 SPS去激活指示。 上行资源 状态信息还可以为第二基站通过 MAC CE、 RRC消息或上行控制信息发送的 上行资源状态。
功率确定模块 12,用于根据最大上行发射功率为 UE配置上行发射功率。 功率获取模块 11获取 UE分配的最大上行发射功率后,功率确定模块 12 根据 UE分配的最大上行发射功率为 UE合理配置上行发射功率, 控制为 UE 分配的上行发射功率不超过 UE 的最大上行发射功率, 或者适当的下调 UE 发射功率。
